Multifunctional scaffold for composite protection construction of easily desertified collapsible loess slope

The invention relates to the technical field of building construction, in particular to a multifunctional scaffold for composite protection construction of a sandy collapsible loess slope, which comprises two vertical crawling ladders, a balance assembly and an anti-sinking assembly, the balance assembly comprises a support platform, a first buffer arm and two groups of pulley mechanisms, each pulley mechanism comprises an arc-shaped sliding way and two guide pulleys, an arc-shaped face is arranged in each arc-shaped sliding way, the anti-sinking assembly comprises two arm stretching mechanisms, each arm stretching mechanism comprises an arc-shaped stretching arm and a second buffering arm, and the two vertical crawling ladders are connected through two connecting assemblies. The contact area between the lower end of the whole scaffold and sandy loess can be increased through the sinking prevention assembly of the device, the situation that the stability of the scaffold is reduced due to the fact that the low
